RF Remote Control Blog

Overview: “I am looking for a remote and multiple receivers for a small private airport. We have a controller box switch that activates when you key the microphone 7 times on a specific frequency. I would like to plug a dc power adapter into this unit and wire into one of your remotes. The runway lights are all solar dc leds. I will need 12 receivers total to start out. My question is: Can one remote, controlled by external wires, send a signal out to multiple receivers at the same time?  In other words, if the remote detects dc input and sends out an ON signal, can several receivers receive the ON signal at the same time?” Solution: We recommend the low voltage triggered transmitter (CB-2V) and 1 channel 2000m receivers (S1L-DC12-ANT2). The most remarkable feature of this transmitter is low current triggered. That is to say, when you offer dc power 5~28V to this transmitter, it will send signal out to the receiver. The receiver is long range with external extended anten...

Question from customer: What we need is three movement detectors with 2 receivers. The receiver can be one channel. Once there is a trigger to any one movement detector this will trigger both receivers at the same time. Each receiver can have one dry contact output that will trigger anytime any of themovement detectors trigger. And the receiver will go back to previous state after 1 minute. Answer: We recommend rf remote receiver and infrared motion sensor (S1DA-DC12-ANT2+W-01) to you. You can have those 2 receivers paired up with three motion sensors so that they can work together. The receiver is delay time adjustable (0 seconds ~ 99 hours). It controls lights, motors, fans, electrically operated doors/locks/ windows/ blinds/ cars or other appliances. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless signal can pass through walls, floors and doors. With the extended external antenna, its working distanc...

Question from customer: I am looking for a radio transmitter receiver 1 channel, 24V, 500 to 1000m, and function: I support the button, close the relay; I loose the button, open the relay. Answer: We recommend the model of 1 channel Momentary 2000m remote control kit (S1M-DC24-ANT2& CB-1). Remote control kit with momentary mode is often used to control motor open/close for electrically operated door/lock/window/blind. Press and hold the button on transmitter, start the motor (close the relay); release the button, stop the motor(open the relay). With external extend antenna, its working distance can reach 2000m (6000ft) theoretically. We have three standard voltage: 9V, 12V, 24V. You can choose the 24V. Owing to one relay on the receiver, it won’t realize that DC motor runs in forward and reverse. It only switches off/ on DC motor. And it is normally open and close relay contact, generally speaking, you should add additional power supply to control...

Sometimes, you want to remote control more than one electric devices just with one transmitter，but most of remote control systems only allow one command at a time to remote control one device even though they are able to activate 2 or more relays. Or you are just looking for a remote control system with range of only 100m that will allow the activation of least three or four commands simultaneously and then trigger three or four channels on the receiver at the same time. Actually, you thought can be realized if the 4 channel 12VDC long range receiver ’s interior circuit can be changed and pair with 1-button transmitter . You just need only one button on the transmitter that you can remote control 4 devices. Its working distance is beyond your thought. It can reach 2000m (no obstacles). You wire either AC 110~240V or DC0~28V electric devices to receiver because of its normally open and closed contact terminals. Electric devices usually wire to normally open terminals for safety purp...

This 1 channel dc rf remote control system operates in 315/433MHz frequency, voltage of AC110~240V or DC0~28V. It is great for hard to reach lights or other DC/AC electrical devices, remote distance is up to 2000m. Applications include light remote control, electric gate remote control, electric window / blind remote control, etc.   More details Online shop:  http://www.carymart.com/

Question from Customer: I’m looking for solution to remotely control fireplace chimney fan on roof of hi-rise building. Desired range would by over 150- 300ft. Fan is 110v, around 2A. Power source would be on roof and antenna would be on roof. Please let me know if you have hardware solution. Answer: 1 channel 30A long range remote switch (S1PX-AC220-ANT2&CB-2) is very suitable for you. With 30A current and AC100~240V voltage direct output, you don’t have to provide additional power supply to controlled fireplace chimney fan because it can get power from powered receiver. The receiver is installed a external extend magnetic antenna, it will help receiver to amplify RF signal reception so that its working distance can reach 2000m(6000ft) outdoor. It is applied to hi-rise building and long range between two buildings. The transmitter enhances its transmitting function to match this kind of receiver. The wiring procedure is simple. Look at the following picture. Wire fan’s mo...

Question from customer: I need a one channel, 12 volt, one button toggle on off switch, heavy duty for outdoor wet, dusty rough vibrating conditions. This devise will be mounted on a concrete pump and will need to operate from a distance of 200m with obstructions. Answer: We thought that you should have high power and long distance remote controller. We recommend this 30 ampere multi-mode long range remote control (S1PU-DC12/24-ANT2 & CB-2). This 1 channel 30A long range remote control operates in toggle, momentary and latched mode (set the mode as you like freely). It can be used to control lights, motors, electrically operated doors / locks / windows / blinds / cars or other appliances with AC110~240V or DC0~28V. With external extend antenna, the transmitter and receiver have longer working range, up to 2000M. Now we’d like to show you how to remote control 12V concrete motor. See the wiring diagram below, B is normally open terminal; C normally closed terminal and A co...

Question from customer: I need a radio system for switching a receiver of an underground garage, by a concrete slab with steel reinforcement and about 30 meters Distance 1st floor. The receiver may be 220 volts. Transmitter I want to act with an external contact. (Connection to a car alarm system). Answer: We recommend the 1 channel high power receiver (S1PUA-AC220-ANT2) and long range transmitter with extended wires (CB-2N). The receiver is activated by ac 220V, which is about 2000m working distance with external extended antenna. The wireless RF signal can pass through walls, floors and doors. It works with the long range transmitter, which features in two external wires because connection of two wires is its triggering method. According to your requirement, we drew a wiring diagram. Wires on the transmitter should be connected to the contacts of car alarm system. The normally open contacts A&B of receiver should be connected to the garage door motor. And supply additio...
